[Plate XII.] 



The Pieris which we have figured was thought to be new, 

 but has since been ascertained to be Piaacopteryx venata, 

 Butl. We are indebted to Dr. G, B. Longstaff for kindly 

 making this correction. Tiie insect is rather rare, and an 

 account of it will be found in Dr. Longstaff's paper on 

 " The Butterflies of the White Nile," Trans. Ent. Soc. Lond. 

 1913, p. 31, pi. ii. fiss. 1 c?, 2 ?. 



We have 2^6 from Kengon, and 1 ^ from Panikwari, 

 April ; South Soudan. 



Pembajordani, sp. n.

 well-defined markings of the fore wing, and the black 

 patagia.

 dirty grey beyond, with sooty-black markings. A faint 

 thin basal line ending in a dark patch on costa and reaching
